[0039] The soup food cooked by the traditional soup cooking barrel is naturally cooled to 40-50℃, which needs about 3 hours, and the food is easily polluted by dust and splashes during the long cooling process. The cooling soup cooking barrel can quickly cool the food and provide the food at a suitable temperature for people, and ensure food hygiene.
[0040] Embodiment 2
[0041] Embodiment 2 is a cooling tea kettle facility, as shown in Figure 9 、 Figure 10 、 Figure 13 The cooling tea kettle facility mainly comprises a cooling kettle 26 part, an outer discharge passage connecting passage 5 part, a water supply pump 20 part, a circulating pump 21 part, a water collecting tank 9 part, and a support platform 13 part, as shown in Figure 13 、 Figure 14 The cooling kettle 26 mainly comprises an inner layer 6, a flow guide cover 7, an input passage 2, a power coupler 23, and an electric heating disc 11, as shown in Figure 14 The inner layer 6 is made of 304 stainless steel with a wall thickness of 0.4 mm. The flow guide cover 7 is arranged outside the inner layer and has a double-layer structure. Polyurethane foam insulation material 18 is filled in the double-layer structure for heat insulation. The inner surface of the flow guide cover 7 has a 3 mm spacing with the inner layer 6 to form a heat exchange passage 1. As shown in Figure 14 、 Figure 11 A small part of the top of the flow guide cover 7 has an increased spacing with the inner layer 6 to form a cavity 19. The cavity 19 is connected with the input passage 2. The input passage 2 has a handle shape to form a handle of the cooling kettle 26. The outer surface of the handle is covered with the heat insulation material 18. As shown in Figure 14 、 Figure 11 The electric heating disc 11 is tightly installed on the outer surface of the bottom of the inner layer 6. The female head of the power coupler 23-1 is installed below the electric heating disc 11. The female head of the power coupler 23-1 is used to connect the power supply of the electric heating disc 11. The side wall of the bottom of the inner layer 6 extends downward to form a flow cover 27. The flow cover 27 and the lower part of the flow guide cover 7 form an outer discharge passage 3. As shown in Figure 13 、 Figure 14 A circular butt joint seat 24 is arranged in the middle of the top surface of the support platform 13. The diameter of the butt joint seat 24 corresponds to the diameter of the bottom of the cooling kettle 26. The butt joint seat 24 is arranged below the outer discharge passage connecting passage 5. The outer discharge passage connecting passage 5 has a funnel shape for easy installation. The outer discharge passage connecting passage 5 is composed of two parts. The two parts are fixed and sealed by screws 16 and sealing washers 14. The outer surface of the outer discharge passage connecting passage 5 is covered with rubber insulation cotton insulation material 18. As shown in Figure 14 、 Figure 12As shown, the outer row channel connecting passage 5 is installed with a power coupler protection bracket 28, which is a cylindrical structure as a whole. The male head of the power coupler 23-2 is installed in the middle of the protection bracket 28, so that the cooling water cannot splash on the male head of the power coupler 23, thus protecting the power coupler 23 well. When the cooling kettle 26 is placed on the docking seat 24, the male head of the power coupler 23-2 is combined with the female head of the power coupler 23-1, thus connecting the circuit of the electric heating disc 11. As shown, Figure 9 、 Figure 10 、 Figure 13 As shown, the water collecting tank 9 is arranged below the outer row channel connecting passage 5, and the lower end of the outer row channel connecting passage 5 penetrates through the upper surface of the water collecting tank 9 and is inserted into the water collecting tank 9. The outer surface of the water collecting tank 9 is covered with rubber and plastic heat insulation cotton heat insulation material 18. As shown, Figure 9 、 Figure 13 As shown, the water supply pump 20, the circulating pump 21 and the backwater pipeline 22 are installed on the table top of the bracket table 13 above the water collecting tank 9. The water inlet of the water supply pump 20 and the water inlet of the circulating pump 21 are connected with pipelines penetrating through the upper surface of the water collecting tank 9 and being inserted into the water collecting tank 9. The lower end of the backwater pipeline 22 penetrates through the upper surface of the water collecting tank 9 and is inserted into the water collecting tank 9. The water outlet of the water supply pump 20 is connected to the input channel 2 through the input channel connecting pipeline 4, which is a quick connector pressure hose (a mature product in the market), and can be connected and detached with the handle of the cooling kettle 26 (the input channel 2) conveniently and quickly. Figure 15 As shown, the cooling kettle facility needs to be used in combination with a titanium evaporator cold water machine, which is a mature product in the market and will not be described here. When the circulating pump 21 and the titanium evaporator cold water machine are working, the water in the water collecting tank 9 is continuously sent into the titanium evaporator by the circulating pump 21 for cooling and temperature reduction, thus maintaining the low temperature state of the cooling water in the water collecting tank 9.
[0042] The use method and working principle of the cooling kettle facility in Example 2 are as follows:
[0043] The cooling kettle facility has very good use effect in commercial occasions. The use method and working principle of the cooling kettle facility will be described below by taking a commercial use occasion as an example. Figure 15As shown, fill the water collecting tank 9 of the cooling tea kettle facility with water, turn on the power of the device to standby, the cold water machine and the circulating pump 21 work in the standby state, the water in the water collecting tank 9 is circulated and refrigerated to reduce the temperature until it reaches the set low temperature value (usually 5°C), and the set low temperature value is maintained. Place the cooling tea kettle 26 on the docking seat 24, fill the cooling tea kettle 26 with boiling water (about 90°C), and put tea leaves and ingredients such as jasmine flowers, chrysanthemum, medlar, longan, longan meat, rock sugar, and milk into the cooling tea kettle 26. Then touch the start key on the device, the electric heating plate 11 is powered on, the water in the cooling tea kettle 26 is boiled, and the electric heating plate 11 is powered off when the set time (usually about 2 minutes) is reached. The water pump 20 starts to work. Figure 13 、 Figure 14 As shown, after the water pump 20 starts to work, the low-temperature cooling water in the water collecting tank 9 flows out of the water outlet of the water pump 20, enters the cavity 19 through the input channel connection pipeline 4 and the input channel 2, and then the low-temperature cooling water in the cavity 19 is collected. After that, the low-temperature cooling water in the cavity 19 is collected, and the high-temperature boiling tea water in the cooling tea kettle 26 is heated through the heat exchange channel 1, so that the high-temperature boiling tea water in the cooling tea kettle 26 is cooled and the temperature is increased. The cooling tea kettle 26 is cooled to the appropriate drinking temperature of 40-50°C, and the water pump 20 stops working. After about 5 seconds, when the remaining water in the heat exchange channel 1 of the cooling tea kettle 26 is drained, hold the handle of the cooling tea kettle 26, take out the cooling tea kettle 26, and pour the tea water at the appropriate drinking temperature into a cup for people to drink. During the cooling process, stir the tea water with a spoon to speed up the cooling process. The start and stop time and sequence of the heating plate 11, the water pump 20, and other electrical components are controlled by an electrical program, and the whole process is automatically completed by one key start.
[0044] The tea water and ingredient juice of traditional milk tea are prepared in advance, and the prepared tea water and ingredient juice are mixed and stirred with milk to make milk tea, which is not fresh and not healthy. Moreover, the food materials are not cooked at high temperature, so the taste is not pure. The cooling tea kettle facility can be used to cook milk tea, which is fast and healthy, and truly realizes the original taste, freshness, nutrition, health, and hygiene of milk tea. It will be a revolution in the milk tea industry and has a broad market prospect.
